Methods #

The sendUssd runs the ussd normaly without a response.
The sendAdvancedUssd (single session call) runs ussd in background and gives you the response as a string. It only surports android 8+(SDK 26+). It defaults to sendUssd when the SDK is lower. For multisession USSDs, send the request as one, ie;

UssdAdvanced.sendAdvancedUssd(code: "*123*1*4*3#", subscriptionId: -1);
copied to clipboard

The multisessionUssd runs a multi session call giving all the sessions response as String. One can interact with the ussd dialog by sending a message using sendMessage method and canceling the session by calling cancelSession

Selecting SimCard #
You can select which simcard to use providing subscriptionId.
-1: is for default phone setting.
Only supports android 6+, and defaults to default if the SDK is lower
Support the plugin
